With the price of fuel going through the roof , has anyone considered converting their mi16 to gas ...46p per litre ... conversion cost around £1500 + vat ..at 12000 miles per year the cost is recouped after 2 years then the fuel is bought at litrally 1/2 price ..loss of power minimal , but i could live with that .... am thnking bout it but cant afford the money till at least next yr ..will see what condition it is overall at next mot and decide then ...

I personally wouldn't bother as i think they are economical as they are. haven't driven a car as good yet.

Keep it below 4000rmp and it's fine on fuel!

drive your car steadly, stay of full throttle and it will do good on fuel.

Im reguarly getting 32-35mpg in my 309 goodwood and thats running a 1.6 8v

going to Lpg just adds loads more weight, which slows the car down. only really worth it in a V8 powered car.

my point being that i love the mi16 , dont really speed ( i havent bought the mi to go fast , just because i love the style and drive of the car ( ive had 4 405s ) i could afford a new car , but i just like driving these ...extra wight isnt a problem though ... 35 mph is ok BUT with lpg i would get equivelent to 60 mpg ( with lpg being 46p per litre) ....

I'm considering buying a 205 diesel, but i would never put lpg in my mi :|
1.40/liter in the netherlands, thats with discount!
Thats 0,92 GB pounds....

More to the point, does anyone makean ECU for an old/rare car like the Mi16, that will allow it to run on gas?

Answers on a pinhead to...

I think there are plans to increase the tax on LPG within the next few years, so the savings might not be so much.

If I had to get a 2nd car I'd go for a diesel and run it on vegetable oil. You can buy it in bulk for 25-30p per litre, and you can now use upto 2000 litres per year without having to pay any tax on it.

I heard that the price of conversion is much lower if your car hasn't got a plastic intake mainfold, it's about half price actually.

That is if ph2 has a plastic mainfold, am I right or am I not?

I have been quoted for the phase 2 mi16 , so no problem there .as for tax on it , they have been saying that for 5 or more yrs , in which time the gas has gone up by 5p per litre IIRC ...and as the saying goes ..two things are certain in life ..death and tax ..

Ideally what you need is something like the Haltech E6X which has dual fuel/ignition maps, which can be changed at the flick of a switch. LPG ignition curves are very different to petrol curves. You need more advance down low and less up high. Most people fail to alter the ignition curve then complain about the poor performance of LPG.

Im in the fortunate position that my Brother in Law has his own business specialising in Vehicle electronics , he did his own conversion a few yrs ago on a Vauxhall Omega , although he doesnt do them now , he knows the very best locally who would do it...... When his car was written off recently he got a payout on the car of £2800 ( without the gas it would have been worth £600-£900) ...He thought he would be cheeky by asking the assessor for that amount but he bit his hand off ( due to the future loss of cheap fuel)

I have LPG in my mi16 (d6c) I can run bouth on Lpg and Gasoline. I have direct injection LPG and costed me i little more than 1000 Euros

Thats the thing , its switchable , although youd be mad to use petrol when the gas was available ..how much do you pay per litre ?? Last week i went away for a long weekend down to Clacton on sea , ( went in the mi) i put in £105 of fuel and over the course of the weekend did 750 miles ...so doing about 35ish to the gallon ...
Not too bad , our Laguna does 39 to the gallon overall , but thats probably a more modern engine ....

One liter of LPG is around half Euro and gasoline (eurosuper 98) is more than 1 Euro so Im driving in half price, and i didn't lose any performance at all runs same on LPG and Gasoline!!

Boll**ks to that! foot to the floor right up to speed limit, and a bit , you actually save more fuel that way than driving like a dodery old fool.
Fully laden boot 4 adults 358mls 90mph 30quids worth of fuel, not bad as when i done the same in my bm but with 2 adults less i actually used 10quid more

My fuel consumption is fine! Probably drinks a lot more than other cars, but I dont care. I bought the car knowing this so I'm in no position to moan!

Same here , but better fuel consumption would make the car perfect ...wouldnt it ??

358 miles out of £30 of fuel?? You're aving a laugh surely? That would be 54mpg!

Well I dont know about perfect...

I promise you not, what reason would i have for lying to you as in the end i would only be kidding myself.
My only problem is will i still maintain this when the new lump goes in......
A bloke i work with thinks i'm pulling his chain as he says its more economical than his yamaha fzr 1000 and in response i gave him my mobile and told him to ring my wife at the time and ask her, he would have to dial as then i couldn't promt her.
He never asked again as i wasn't lying.

Oh, btw my ph2 was crap on fuel, and you can ask my partner as she used the ph2 while i used the ph1, she always moaned about the amount of fuel she used to me. Ha ha i never swaped with her no matter how much she begged.

After doing nothing about it for a few months i finally phoned the fitter today and enquired about the conversion ...it is something like £1300 plus vat ...
Bearing in mind that i do at least 400 miles per month the savings would be massive ( might be doing 110 miles a day soon , depending on which job i go to ) ... the only niggle which ive had is one of the plastic inlet manifold , they had , in the old systems , been known to blow them apart , with pressure/fuel build up , but on the new system they are direct injection ..so happy days ..

the only thing im waiting for now is to locate this flat spot ..am eliminating things one by one , next is a replacement ecu and then a replacement manifold , im waiting for them to arrive now ..£40 posted for them both

To be honest with the difference between the price of fuel and lpg ( allowing for the loss of mpg with lpg ) , im expecting the system to pay for itself in 12 months instead of my original 2 yr expectations ..


As far as all the predictions of tax rises on lpg , my gut feeling is that ( after the price freeze in 2009) that it will rise in line with petrol ( ie 2p per litre per budget ) , but still miles lower than petrol ....

It's a no brainer in Australia now, with the government giving a $2000 rebate towards the cost of the conversion, which is typically $2500-$3000. I've been trying to talk my son into getting his Mi16 converted as he travels 60km per day. It would only take 4 months to break even.

ive just reread my last post and realised ive made a mistake on my mileage , its not 400 miles per month , its 400 miles per week ...
Ive been doing my research as to whether to just get rid of the car and buy a cheap ax diesel , which will do , according to citroens brochure , a massive 78 miles to the gallon at 55 mph 56 at 75 mph and 54 mpg around town ..but i know i wont be happy unless ivee got a 405 mi16 , so taking into consideration the cost of lpg , my mi , once converted , will be comparable ...so like Petert said , its a no brainer

Just been rereading the old post on LPG and have had this response on various forums , well 2 yrs on since this reply and like i predicted , this just hasnt happened , the govenment hasnt taxed it to death , in fact the local supplier of lpg conversions is still selling lpg at 46p per litre ..

Sounds a bit expensive. We buy it for AUS 49c/L.

how much do you pay for regular 95 octane? its around the £1.02 to £1.09 at the moment here.

Mate , Everything here is expensive

$1.10 to $1.25/L
